Summary: On 16 Feb., acceptance of the EI report of Haili Guixi's carbosulfan TC expansion project was announced by local authorities. The company plans to expand its production capacity for carbosulfan TC by 3,000 t/a. As regards Haili Guixi's 3,000 t/a pirimiphos-methyl TC project, though it acquired government approval last year, the construction work has not started yet.

On 16 Feb., the environmental impact (EI) report of the new production lines building project (namely carbosulfan TC capacity expansion project) of Haili Guixi New Material Technology Co., Ltd. (Haili Guixi, formerly known as Haili Guixi Chemical Pesticide Co., Ltd.) was publicised by local authorities. The company, located in the Sulphur & Phosphorus Chemical Industry Base, Guixi City, Jiangxi Province, plans to expand its carbosulfan TC capacity from 3,000 t/a to 6,000 t/a. It's worth noting that carbosulfan has enjoyed rapid growth as more restrictions were put to the use of carbofuran in China.

Besides, Haili Guixi's 3,000 t/a pirimiphos-methyl TC project was approved by the Jiangxi Provincial Department of Ecology and Environment in March 2022, but the construction is yet to start. Pirimiphos-methyl is an organophosphorus insecticide with high efficacy, low toxicity and low residue, which is mainly used for the control of pests and mites in warehouses, granaries, livestock sheds, courtyards and industrial premises. Particularly, it can keep effective for a long period against white flies, thrips, scale insects, aphids and mites on tomato, cucumber, pepper, eggplant and other vegetables. It is one of the most efficient and economical insecticides currently available for application in storage sites.

Although Haili Guixi does not hold any pesticide registration certificate for pirimiphos-methyl TC, its parent company Hunan Haili Chemical Industry Co., Ltd. (Hunan Haili) has already obtained a registration certificate for 90% pirimiphos-methyl TC (registration No. PD20081556). So far only three enterprises have had pirimiphos-methyl TC products registered in China, all in 90% active ingredient (AI) content. The AI has also been registered for hygienic use; there are 12 hygienic insecticide products containing pirimiphos-methyl registered in China, which are mainly used for the control of indoor mosquitoes and flies. It should be noted that Hunan Haili holds the only pirimiphos-methyl registration (mixed with deltamethrin) for the control of stored-grain pests in China. As the use of chemical pesticides for the control of stored-product pests decreases and pest resistance increases, pirimiphos-methyl mixed formulation products with deltamethrin, or even spinosad, may become the mainstream in the future.
